So, How do You Know?
If your waterproofer is not using 4" perforated, flexible coil, A.D.S. drain pipe, they do not have any experience. In addition, if this were a new building, they would be violating new residential building code, and violating engineering standards. They are simply using a "gimmick" or "cookie-cutter" approach. License and franchise operations constantly do this, using box pipes with large holes, 2"-3" in diameter. They also constantly forfeit or dissolve their corporate structures.
If your waterproofer is not installing 4" perforated drain pipe alongside the footing, below the level of the floor, but installing 2" or 3"on top of the footing, they do not have any experience. Again, if this were a new building, they would be violating new residential building code, and violating engineering standards. Pipe must be installed below the floor level, alongside the footing, but not below the footing, either outside or inside. And with a wide trench.
If your waterproofer is wrapping the drain pipe in filter fabric, they do not have enough experience, as experience will show this method to be ineffective. (See Photo Gallery) All Filters Clog! This is why we change our oil filters, our coffee filters, our air filters, water filters, gas filters, AC filters, etc, etc. This is a fact. If drain pipes are wrapped with filters, they will fail within 3-5 years. If your waterproofer is not using round washed gravel, substituting crushed gravel, they don't understand that crushed gravel is used for compaction, and round aggregate is used for drainage.
